SUSE SLES12 Security Update : kernel (SUSE-SU-2018:1007-1)

High Nessus Plugin ID 109256

Synopsis

The remote SUSE host is missing one or more security updates.

Description

This update for the Linux Kernel 4.4.74-92_38 fixes several issues.
The following security issues were fixed :

- CVE-2017-13166: Prevent elevation of privilege vulnerability in the v4l2 video driver (bsc#1085447).

- CVE-2018-1068: A flaw in the implementation of 32-bit syscall interface for bridging allowed a privileged user to arbitrarily write to a limited range of kernel memory (bsc#1085114).

- CVE-2018-7566: Prevent buffer overflow via an SNDRV_SEQ_IOCTL_SET_CLIENT_POOL ioctl write operation to /dev/snd/seq by a local user (bsc#1083488).

- CVE-2018-1000004: Prevent race condition in the sound system that could have lead to a deadlock and denial of service condition (bsc#1076017).

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
